'Patented Apr. 3o, 1912.

Application led December 27, 1909. Serial No. 535,089.

To all 'whom it may concern: b

Be it known thatI, HENRY C. HonGEs, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Roller-Bearings, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being -had to the accompanying drawings, which form apart of this specification.

This invention relates to roller bearings.

It has for its object an improved roller bearing in which the roller -is held at one end andv allowed to swing at the other end and to roll freely, and thereby the bearing is peculiarly adapted to support an oscillating or rotating member against the end thrust thereof. Such bearings -are useful in supporting vertical shafts or arbors, in supporting railway cars upon their holsters, vehicle bodies on axles, and many other similar constructions in which one body oscillates or rotates with respect to another.

In the drawings :'-Figure 1, is a sectionacross the shaft and diametrically through the bearing. system. Fig. 2, is a plan view of the bearing cylinders. Fig. 3, is an elevation of a cylinder and a sectional view of the seat in which the cylinder is held. Fig. 4, is a detail drawing of the parts constituting a roller and its seat.

The complete structure in which the invent-ion is embodied embraces the anti-friction rollers of a roller bearing, a cage in which the bodies of the anti-friction rollers are contained, and ball sockets or spherical sockets in which heads connected with the bodies of the anti-friction rollers are held. Each bearing roller l has a cylindrical body, from which there projects at one end a spherical head2 which is connected to the body 2'L by neck 2b. The body part 2 is held in a compartment or chamber of the cage, which compartment is narrow at that end from which the spherical cavity extends and widens from the fartherl end ofthe anti-friction rollers to allow a sufficiency of swing or play to this free end of the roller. That part of the cage which comprises the spherical socket is made in two parts, the base part 6a and the cap piece 6. In the base is one-half of the spherical cavity 7.l and in the cap piece is the other half. The" head 2 engages in a spherical cavity; the neck 2b of the roller engages in a throat passage 5 and the walls of the throat.pas' sage prevent the roller from escaping or Afrom having any freedomof movement at4 the head end of the roller except freedom to rotate on its axis and to swing on the head.'

A bearing plate 8 engages over the rollers, and this bearing plate may be used as a thrust plate for* the collar 9 on the shaft, or may be'itself secured to the shaft, as may be best adapted for the special purpose to which the bearing is applied.

What I claim is .1. A pivotal bearing comprising a cage provided 'with a plurality of sector shaped chambers having socket cavities at their narrow ends, a roller engaging in each chamber having a globular head freely socketed in each cavity and adapted thereby to permit the said roller to oscillate through the limits of said chamber.

QI The combination of a segmental cage having a plurality of sector shaped chambers, each provided with a semispherical cavity, and a neck passage connecting said cavity with the narrow end of said cham'- ber, a detachable cap plate having semispherical y.cavities registering with the semispherical cavity of the cage, a roller provided with a globular head socketed in said sphericalV cavity and adapted to be limited by the swing of the body portion within said chamber.

In testimony whereof, I sign this `specification in the presence of two witnesses.
